Moving from 1GB to 1.5GB will only make a lot of difference if you are regularly bumping up against the memory ceiling.
Since you're asking this question, I doubt that you are.
One way to find out is to Right-click your taskbar and open the Windows Task Manager.
Click the Performance tab, and look at the values listed under the Commit Charge (K) and Kernel Memory (K).
If your Peak commit charge + Total kernel memory is less than your total physical memory (listed under Physical Memory (K) > Total), then you have never hit your memory ceiling.
For example, my common scenario here at home would be running WOW, a few web browsers, watching an xvid .avi movie and have photoshop open. I'm using about 1400MB. I'd be fine with 1.5GB, but for technical reasons having to do with the Athlon 64 architecture, the memory controller, and early motherboards, I'm running two 1GB modules.
